The plants in the shallow pot are Japanese variegated sedges, which are evergreen in Dallas. They get a little ratty toward winter's end & need a spring trim, but that's all. The plants along the center and by fountain are dwarf germander (Teucrium chamaedrys) which are also evergreen, and have a nice tiny purple tubular flower which attracts hummingbirds. It needs more sun than this sun for better blooming, but we just wanted the structure here. Typically it is sheared, which reduces blooms; it's used a lot in English knot gardens. Larger dark green ball-like shrubs are small boxwoods, also evergreen and they like the alkaline soils in Texas.

hope that helps!
